During I&S class we had a segment showing examples of whether the human race has become the way it is via Nature or Nurture. Here is what I think the argument concludes :

Nature :

Having specific qualities genetically, not forced.

Nurture :

Having been taught to have certain qualities or ways of thinking, forced.

In my opinion, I think that humans have evolved in the way they have because of both nurture, and nature. For example, African Americans were forced, nurtured into slavery and because of that their running nature has changed. In conclusion, events, beings, and things in our environment has led us and evolved us into doing things by nature, and formed who we are today.
